Applioation filed March 20, 1913. Serial No. 755,5B6.

To all whom it may concern:

Be it known that I, AaoLrHUs S. DENNIS,

a citizen of theUnited States, residing in Lakewood, in the county of Cuyahoga and State of Ohio, have inventedcertain new and useful Improvements in Type-Writing Machinest of which the following is a specification.

This invention relates to work-holding or feeding devices of typewriting machines.

One of the objects of the invention is to provide for proper holding and feeding of cards or narrow sheets, and'particularly with a view to facilitating the writing near the edges of said cards, and especially the side and bottom edges of said cards or sheets.

In the Vmachine illustrated herein, the side edges` of the work-sheets are held against the platen by means of thin flexible bands which are tautened against the platen and are adjustable along the same to accommo` date the width or position of the work-sheet, these bands extending from below to above the printing line and each band being caught Vat both top and bottom ends; a pressure roll while the flexible bands hold the side edges'- lthereoi1 against the platen, so that the sheet may alw'ays have a firm backing where it re ceives the type impressions. guides may be provided with scale marks so that they thus act as gages; and in order to l avoid difficulty from the work-sheet jumping above the frame guides when the platen is shifted up to print capital letters, during the writing of the last line on the work-sheet,

I arrange to shift the frame guide, gages or scales up and down with the platen. These frame guides or gages normally register with the bottom of the printing line on the platen, and owing to their length, they collide with the ends of the platen carriage when they are shifted up with the platen for writing capi- ,tal letters. In order to avoid trouble from These frame such collision, the outer ends of the frame guides are beveled, so that the 'carriage end operates to force the guides down, so that no harm results.

The side bands are arranged to slip between the frame guides and the platen and also lbetween the usual ribbon 0 `and readily applicable to existing machines.

In the accompanying drawings, Figure 1 is a front elevation of a platen and paper carriage of anUnderwood front-strike type-k writing machine embodying my present improvements; the parts being shown in lowercase positions. Fig. 2 is asimilar view show-V ing the parts shifted upto upper-case positions. Fig. 3 is a'sectional side elevation showing a type about tofstrike the platen; the parts being in the same position as at Fig. l. Fig. 4 is a perspective viewof a. guard or shield used at the backof the rib bon to prevent fouling of'the same with the guide bands for the sideV edges of the sheet.

Fig.y 5 shows the platen shifted up for print-4 ing capital letters, together with the frame guide, gage or scale, etc. Fig. 6 is aiperspective view of one of the shiftable carriers on which a frame guide, gage orscale is mounted. Fig. 7 is a perspective view of one of the frame guides, gages or wing scales. Fig. 8 shows a bracket which .is intended for mouiitingon the usual type bar 'segmentto carrya linkage for one of the frame guides or wing scales. Fig. 9 is 'aview to illustrate how the carriage end cams down the frame guide or scale from the dotted line to the full line position (independentlyof the opposite, guide or scale) as the carriage moves in letterfeeding direction.

" In the Underwood typewriting machine, types l' strike against the front side of a revoluble platen 2, which is mounted by an axle Sin the ends 4 of a platen frame, which comprises a paper-shelf 5 and has on its side the usual releasable front and rear bottom feed# ing rolls 6, 7. The types are provided on the iao a cross-piece 11'; and a springl 12 bearing yiagaiist said cross-piece 1l holds a key 13 'in a longitudinal groove 1l in the rod 10 .torvhold' the .pressure roll 8 against'the platen; said key being guided in slots in i said` armsfly., Said rod is fastened at its ends to av pair of arms 15 to form a baih, which is hinged or pivoted at 16 to brackets 1 fixed by screws 1S upon the platen frame ends 4, said brackets extending ldown be- 2 tween the yplaten and the platen frame ends.

, with the pivots19 ofthe front pressure rolls The screw pivots 16 may be concentric "Y so that when the rod 10 is swung forwardly out of normal position, the rolls'will either remain on the platen or near the same. Each mount can'be rocked upon the rod 10 y'to swing the rolls entirely away from the platen, so that the operator has the choice yeither of swinging the rod forwardly while leaving' the,- rolls on or near to the platen, or else of swinging the mounts and rolls upwardly. .There extends downwardly from the loweor forward end of each mount, a, shorthand 20which is flexible and springy' andmay consist of a. very thin steel spring, although anyl other material may be used. Thelcwer end of this band may be caught upon a rod 21,"which at its ends is fixed in the lower ends of the brackets 17. These bands are held, taut against the platen, and

this, it will loel understood, is done withouty releasing the pressure ,of the rolls 8,- On the contrary, thepull of the band lmay augment the pressure of said rolls. "L

The bands are'feficient paper feeders, and taken in connection with 'the rolls, make a very satisfactory device for this purpose. lThe lower ends of the bands maybe only slightly hooked around the rod 21, as at 22, and this will permit the bands to be unhooked when it is desi-red to swing up the arms'f). 1n order to unhook them, itjis only necessary to swing the rod 10 forward a little, and then swing the mounts around the rod. lt will be seen that either front paper guide may be adjusted at anytime to any position required along the platen.

- The bands 20, being thin and lying snugly against the platen, readily pass behind the front gages or scales 23, and they may also easily7 slip behind the usual ribbon 24 and vibrator v25, and the latter may have guards 26, one at each side of the printing point. The guards may be secured at their lower ends in any suitable manner upon the ribbon vibrator, so as t0 leave a space between the vibrator and the guards for the introduction of the ribbon; andthe guards may, at their upper edges, flare forwardly as at 27, so as to be engaged and cammed backwardly toward the ribbon, to prevent 'the latter from being caught by said bands.

The wing scales 23 serve as guides for the lower edges of the work-sheet, and are intended to hold the work-sheet while a line thereof. These guides or gages 23 are mounted to shift 'up and down with the platen 2. The platen is shifted up and down by means of a shift rail 28 in the usual manner, the platen frame 4 having a rod l:'29 upon which is mounted a roll 30 to run upcn said rail 28 as usual.' The rod 21, which of course shifts up and down with the ilaten, is employed for controlling the rising and falling movements of the guides, gages or scales 23; springs 31 tending oonstantly to shift said scales, and pins 32 being connected to the scales andextending under said .rod 21, whereby the latter holds the scales against rising, but permits the scales to rise when the carriage is shifted up from the position at Figs. 1 and 3' to the position at Figs. 2 and 5.l 1t will be seen that the scales are carried on mounts 33 and that the latter are mounted upon bell cranks 3e, 35, one pair at each side of the central type guidegeach pair of bell cranks being pivotedy to a bracket 41 secured to the usual type-bar segment 42, and being connected by a horizontal link 36, so that the scales move up a'i'id down inparallelism..

The upper arms of the bell cranks form parallel links connecting the mounts 33 with their support. Each scale is pivoted at 37 to its mount and pressed bya spring 38 rearwardly against the platen or the sheet thereon to hold the sheet against the platen. ll7henever the platen is shifted up, the rod 21 is carried up with it and the springs 31 are permitted to throw thef links 36 toward -eaeh other and ttherebyfs',wing equally all will partake of the endwise movements of the platen, and will, therefore, have a running engagement with` the pins 32. In order to make these wing .scales of practical value, they must have substantial aieeaa length' j' they may control the', bottom edges of she'h'etsnthat are -nearly theisame width as the carriage, and when the scalesl are made thisileigth, they c ollide with the carriage ends 39,ms occurring because the upper edgesv of the scales must be high enough to register.

(hieV ofthev features of the present invention the proyisionof means whereby such. i0 long scale'slofrjgni'des can be employed notwithstanding the'apparent necessity of reduciiig'ltl 'ir measurements to a size accommo' tedby' the length of the carriage itself.

:Tl'ii'sfobjectfis accomplished by making .theI lsfscales depressible vby mounting them in the 'and ridesover the top edge of the scale as there shown.V The ldotted lines show they position of the scale when engaged by the carriage ends, and rthe full linesk show the ,depression ofthisscale effected by the car- 25 riagev ends...

Thusfa scale of ample transverse --measure ments ymay be ,employed on the machine frame, and hence the machine is rendered suitable for holding wide cards aswell as narrow' cards firmly against the 3,0 platen while thesame are being written upon close ytogrthe bottom edge thereof.

' [Ita ill, he seen scale atv Fig. 9 occurs independently ofthe platenshiftframe or. of the rod 21', since l 5 eitherpin 32 ymay have aldownward movement ,away from" said l rod independently thereof.

placed lclose to the ymiddle of the machine wherethey are'fnot apt to be struck by the 40 bands 20; and

moreover the pins 32 may be made of roundcontour, so that the bands, where vthey 'hook under the rod 2l, may pass freely by. the pins; these bands being of very thin-metal, .and hence not displacing either the pins 32 or any of the other parts to any'extcnt onany occasion. vVariations .may be resorted scope. lof the invention,
